FIRST QUANTUM MINERALS REPORTS FOURTH QUARTER

AND YEAR-END 2023 RESULTS

(In United States dollars, except where noted otherwise)

Toronto, Ontario (February 20, 2024) - First Quantum Minerals Ltd. (“First Quantum” or “the Company”) (TSX: FM)

today reports results for the three months ended December 31, 2023 (“Q4 2023” or the "fourth quarter") of a net loss

attributable to shareholders of the Company of $1,447 million ($2.09 loss per share) and an adjusted loss 1 of $259

million ($0.37 adjusted loss per share 2). For the year ended December 31, 2023, the Company reported a net loss

attributable to shareholders of the Company of $954 million ($1.38 basic loss per share) and adjusted earnings 1 of

$261 million ($0.38 adjusted earnings per share2).

“2023 closed with the Company facing one of its biggest challenges in recent history. However, I am confident in the

resilience of First Quantum and the determination of our teams to work through these challenges. The Company

continues to take a proactive approach to managing its balance sheet and addressing its liquidity in a fulsome and

disciplined manner. As a continuation of these efforts, it is pleasing to share that since the reporting period, t he

Company has signed a $500 million copper prepay arrangement at competitive terms with Jiangxi Copper. This

arrangement is a reminder of the strategic nature of copper as supply challenges abound across the sector.

Constructive discussions with our lenders for an amendment and extension of our loan facilities, which are an

important component to our fulsome solution, are well -advanced and there is a high degree of alignment among all

parties. We continue with sales processes for some of our smaller assets and minority stake sales in our larger

assets, with strong interest from highly credible counterparties for both,” commented Tristan Pascall, Chief Executive

Officer of First Quantum. "In Zambia, we continue to be confident in the investment climate in the country and, as

such, we remain committed to our investment in the S3 Expansion, which is expected to generate significant free

cash flow once operational in the second half of 2025. At Cobre Panamá, the blockades around the mine have

dissipated, allowing for critical supply deliveries by port and by road. We continue to work closely with local authorities

in order to ship the concentrate stockpile from the site, which is required to fund critical environmental work. We

remain focused on the preservation, safe and responsible stewardship of Cobre Panamá. Finally, I would like to

thank everybody at First Quantum for their continued perseverance and hard work in these challenging times."

Q4 2023 SUMMARY

In Q4 2023, First Quantum reported gross profit of $87 million, EBITDA1 of $273 million, a net loss attributable to

shareholders of $2.09 per share, and an adjusted loss per share2 of $0.37. Relative to the third quarter of 2023 (“Q3

2023”), fourth quarter financial results were negatively impacted by the disruptions experienced at the Cobre Panamá

mine which led to the mine being placed in a phase of Preservation and Safe Management ("P&SM"). In addition,

disruptions at the mine's port prevented the shipment of concentrates since the beginning of November las t year.

Total copper production for the fourth quarter was 160,200 tonnes, a 28% decrease from Q3 2023. The quarter-over-

quarter decrease in production was attributable to lower production at all three of the Company's main operations,

mainly Cobre Panamá. Copper C1 cash cost 2 of $1.82 per lb for Q4 2023 was $0.40 per lb higher than in Q3 2023

due to lower production and higher electricity costs at the Zambian operations following the signing of the new

ZESCO agreement, mitigated by lower maintenance costs.

Three-year guidance on production, copper C1 cash costs 1, copper all -in sustaining costs ("AISC") 1 and capital

expenditures that were previously disclosed on January 15, 2024 remain unchanged and exclude Cobre Panamá.

For 2024, copper production is forecast to be 370,000 to 420,000 tonnes while copper C1 cash costs1 are guided to

be $1.80 to $2.05 per lb. Capital cost guidance for 2024 is expected to be between $1,250 million and $1,400 million.

Q4 2023 OPERATIONAL HIGHLIGHTS

Total copper production for the fourth quarter was 160,200 tonnes, a 28% decrease from Q3 2023. The quarter-over-

quarter decrease in production was impacted by the ramp down in operations at Cobre Panamá to a phase of P&SM

due to illegal blockades around the mine site while lower production at Kansanshi and Sentinel also contributed to

the decline. Copper sales volumes in Q4 2023 totaled 127,721 tonnes, approximately 32,479 tonnes lower than

production, mainly due to port disruptions at Cobre Panamá that prevented the shipment of copper concentrates.

• Cobre Panamá produced 62,616 tonnes of copper in Q4 2023, a decrease of 50,118 tonnes from the

previous quarter as production was suspended at the end of November 2023 due to illegal blockades at the

Punta Rincón port and at the roads to the site that prevented the delivery of supplies that were necessary to

operate the power plant. Prior to the disruptions from the illegal blockades, Cobre Panamá operated at an

annualized throughput rate of 93 million tonnes for the month of October. This, combined with higher grades

and improving recoveries, allowed the operation to achieve monthly record production of 41,543 tonnes.

Copper production for the full year 2023 was 330,863 tonnes, down from 350,438 tonnes in 2022. Copper

C1 cash cost 1 of $1.45 per lb was $0.26 per lb higher than the previous quarter due to lower copper

production volumes and lower gold by -product credits. 2024 production guidance for Cobre Panamá has

been suspended as the site currently remains in a phase of P&SM. At the request of the Ministry of

Commerce and Industries ("MICI"), Cobre Panamá delivered a preliminary draft for the first phase of P&SM

on January 16, 2024. Previous illegal blockages around the mine have dissipated, allowing for the delivery

by road and at port of necessary supplies to conduct the P&SM program. The associated costs for the

program are estimated at $15 to $20 million per month and further reductions could follow depending on

environmental stewardship programs. Approximately 121 thousand dry metric tonnes of copper concentrate

remains onsite following disruptions at the Punta Rincón port. The sale of this concentrate will result in a net

cash inflow of approximately $225 million at current market prices.

• Kansanshi’s copper production of 31,887 tonnes in Q4 2023 was 7,713 tonnes lower than the previous

quarter as a result of lower throughput, grades and recoveries across all three circuits. Lower throughput

was primarily due to mining constraints in M17 resulting in slower mining rates and the stockpiling of material

from M15 and M17 due to acid volume restrictions. Kansanshi's production for 2023 of 134,827 tonnes was

within the revised guidance range of 130,000 to 140,000 tonnes. Copper C1 cash cost 1 of $2.43 per lb was

$0.80 higher than Q3 2023 mainly due to lower copper production volumes. Production guidance for 2024

is expected to be 130,000 to 150,000 tonnes of copper and 65,000 to 75,000 ounces of gold.

• Sentinel reported copper production of 59,964 tonnes in Q4 2023, 3,841 tonnes lower than the previous

quarter mainly due to lower throughput as production continued to be impacted by the mi ning of very hard

rock from the lower levels in Stages 1 and 2 of the open pit. Mining productivity, however, continued to

improve during the quarter with improved blast fragmentation and reduced congestion with the

commencement of the Stage 3 (Western Cut-back) mining. Sentinel copper production for 2023 of 214,046

tonnes was lower than the revised guidance range of 220,000 to 230,000 tonnes. Copper C1 cash cost 1 of

$1.85 per lb was $0.20 per lb higher than the preceding quarter, reflecting higher electric ity prices. Copper

production guidance for 2024 is 220,000 to 250,000 tonnes. The major focus for 2024 at Sentinel will be on

the development of Stage 3 (Western Cut -back) in order to enable improved mining productivities and

increased availability of softer material from higher elevations. The wet weather preparations and improved

storm water management processes have been implemented to mitigate the risk of water accumulation as

experienced in previous raining seasons.

• Enterprise produced 2,751 tonnes of nickel during the fourth quarter, an increase from 1,556 tonnes in Q3

2023 as the operation continues to ramp up. Production guidance in 2024 for Enterprise is 10,000 to 20,000

contained tonnes of nickel. Commercial production and full plant throughput is expected in 2024.

• At Ravensthorpe, as previously announced, a decision was made subsequent to the year-end to scale back

mining operations and associated processing activities as a result of continued low nickel prices. A new

operating plan has been dev eloped under which Ravensthorpe aims to maintain production from ore

stockpiles and suspend mining from the Shoemaker Levy ore body. The high-pressure acid leach circuit will

also be bypassed and ore will be exclusively processed through the atmospheric leach circuits. Production

from existing ore stockpiles is expected for 18 months after which time, mining at Hale Bopp and Halley ’s

ore bodies is expected to commence.

FINANCIAL HIGHLIGHTS

Compared to Q3 2023, fourth quarter financial results were considerably weaker due to the suspension of production

at the Cobre Panamá mine at the end of November 2023 when the mine was placed in P&SM. Financial results were

also impacted by approximately 121 thousand dry metric tonnes of copper concentr ate that remains unsold from

Cobre Panamá as a result of the disruptions at the Punta Rincón port. An impairment charge of $900 million was

recognized which includes $854 million at Ravensthorpe as a result of significant margin pressure due to weak nickel

prices, lower payabilities and high operating costs. Impairment expenses also include $46 million in respect of

exploration assets.

The Company's total and net debt1 increased during the fourth quarter due to a one-time payment of $567 million to

the Government of Panama on November 16, 2023 in respect to taxes and royalties for the period from December

2021 to October 2023.

• Gross profit for the fourth quarter of $87 million was 87% lower than in Q3 2023, while EBITDA 1 of $273

million for the same period was 72% lower.

• Cash flows used by operating activities of $185 million ($0.27 per share 2) for the quarter were $779 million

lower than Q3 2023.

• Net debt1 increased by $783 million during the quarter, taking the net debt 1 balance to $6,420 million as at

December 31, 2023. As at December 31, 2023, total debt was $7,379 million (total debt was $6,892 million

at September 30, 2023).

• An interim dividend of CDN$0.08 per share, in respect of the financial year ended December 31, 2023 was

paid on September 19, 2023 to shareholders of record on August 28, 2023. On January 15, 2024, the

Company announced that it has suspended its dividend as a result of Cobre Panamá being in a phase of

P&SM.

The current situation at Cobre Panamá has impacted the EBITDA 1 generating potential of the Company, putting at

risk the Company’s ability to meet the net debt 1 to EBITDA1 ratio covenant as defined in its current senior banking

facilities. Current forecasts for 2024, before taking into account future balance sheet initiatives, indicate the Company

may breach the prevailing net debt 1 to EBITDA1 ratio covenant during the coming twelve months, and failure to

address this would result in the existence of a material uncertainty that may cast a significant doubt about the

Company’s ability to continue as a going concern. Accordingly, disclosure of this material uncertainty has been made

in the notes to the consolidated financial statements.

Management has a strong expectation that the balance sheet initiatives initiated earlier this year will be realized in

the near term. The disclosure of material uncertainty does not include potential changes in the Company's covenants,

which are materially advanced in discussions with the Company's banking partners nor the f inancing initiatives

described in more detail below, which would significantly reduce the risk of breaching covenants if realized.

BALANCE SHEET INITIATIVES

With Cobre Panamá in a phase of P&SM, the Company is employing a number of measures to prudently allow for

the planned capital spending elsewhere across First Quantum ’s business, most notably the S3 Expansion at

Kansanshi, which will further strengthen cash flows when it is commissioned in 2025. The Company is advancing

several initiatives in 2024 to give optionality and flexibility:

• Copper prepayment agreement ("Prepayment Agreement"): After the reporting period, the Company

signed a $500 million 3- year Prepayment Agreement with Jiangxi Copper at competitive rates. The

agreement provides for the delivery of 50kt of copper anode per annum from Kansanshi payable at market

prices. The prepaid amount will reduce in line with deliveries over the second and third years of the

Prepayment Agreement. Proceeds will be used towards general corporate purposes and to increase liquidity.

• Dividend suspension: On January 15, 2024, the Board suspended the semi -annual dividend. The Board

will review the Company ’s financial policy on an ongoing basis and adjust the dividend approach when

appropriate.

• Capital expenditure reductions: Planned capital programs across the Company were reduced or re-

phased by approximately $400 million in 2024 and $250 million in 2025. The Company remains committed

to delivering the S3 Expansion project at Kansanshi in 2025.

• Operating costs and other reductions: Following a detailed review of all operating and administrative

costs, the Company has identified savings which will offset recent inflationary pressures. The cost savings

initiatives include a change in strategy at Ravensthorpe to temporarily remove higher cost production.

• Working capital: The Company is also targeting reductions in working capital requirements and savings in

the procurement of materials, supplies and third party service costs where possible.

• Assets and stake sales: A sales process for the Las Cruces mine in Spain is well -advanced with strong

interest given the strategic location and processing capabilities of the project. Following a number of inbound

expressions of interest, the Company is evaluating the possibility of a minority investment by strategic

investors in the Company's Zambian business.

• Financing activity: The Company continues to take a proactive approach to managing its balance sheet

and the refinancing of its near -term debt maturities. An ongoing proces s between the Company and its

banking partners is materially advanced, with a high degree of alignment regarding amendment and

extension. A conclusion on these amendments is expected in the near term. The Company is also assessing

a range of alternatives across the capital markets to maintain a robust financial position and preserve value

for its shareholders.

2024 GUIDANCE

Guidance is based on a number of assumptions and estimates as of December 31, 2023, including among other

things, assumptions about metal prices and anticipated costs and expenditures. Guidance involves estimates of

known and unknown risks, uncertainties and other factors, which may cause the actual results to be materially

different.

Production, cash cost and capital expenditure guidance for 2024 to 2026 remain unchanged from the News Release

"First Quantum Minerals Announces 2023 Preliminary Production, 2024- 2026 Guidance and Balance Sheet

Initiatives" dated January 15, 2024 and is presented excluding Cobre Panamá as the mine remains in a phase of

P&SM with production halted. The associated funding of P&SM is expected to range from $15 to $20 million per

month and further reductions could follow depending on environmental stewardship programs.

2024 Copper production guidance is between 370,000 to 420,000 tonnes and is expected to increase to between

400,000 to 460,000 tonnes in 2025 and 2026 as the S3 Expansion at Kansanshi comes online. For 2024, copper C1

cash costs1 are guided to be $1.80 to $2.05 per lb. Total copper C 1 cash costs1 and copper AISC1 unit cost ranges

are in line with prior year guidance when excluding Cobre Panamá. Improvements in operating costs such as fuel,

maintenance, contractors and labour mitigated the impact of lower by -product credits from Kansanshi and lower

production at Sentinel.

Capital expenditure continues to experience inflationary cost increases driven by higher shipping rates, steel prices,

power costs, labour rates and general inflation. Guidance reflects these cost increases as well as additional scope

increases and the timing of expenditures, including approximately $235 million of expenditure carried over from

2023. However, strategic measures have been implemented to offset the impact of these inflationary increases and

deferred expenditure through optimizing and prioritizing capital expenditure.

Total capital expenditure for the S3 Expansion project remains unchanged at $1.25 billion, with approximately $215
